Translocation Renal Cell Carcinoma

The researchers are doing this study to find out whether the combination of abemaciclib and cabozantinib is a safe and effective treatment for people with metastatic clear cell renal cell carcinoma (ccRCC) and translocation-associated renal cell cancer (tRCC). The researchers will test different doses of the study drugs to find the highest doses that cause few or mild side effects in participants.

The ANTARES study is a phase II basket trial designed to evaluate the tissue-agnostic efficacy of the monoclonal anti-PD1 antibody, nivolumab, in patients with advanced or metastatic rare tumors. The study aims to treat rare malignancies with PD-L1 expression (CPS ≥ 10), regardless of the tumor's tissue type or location. Patients who have not responded to standard treatments will be included, and treatment will last for up to 12 months. The study will assess objective response, progression-free survival, and biomarkers such as PD-L1, ctDNA, and microvesicles, in a multicenter collaborative effort to provide innovative therapeutic options for this underrepresented population

The goal of this research study is to evaluate how well and safely the study drugs sasanlimab, palbociclib, and axitinib work for treatment of participants with advanced clear cell renal cell carcinoma (ccRCC) or translocation renal cell carcinoma (tRCC). The name of the study drugs involved in this research study is: * Sasanlimab (a type of monoclonal antibody) * Palbociclib (a type of kinase inhibitor) * Axitinib (a type of Vascular endothelial growth factor inhibitor)
